TUG-GEAR.

Specification of Letters Patent.

' Patented Nov. 1914.

Application filed June 4, 1914.. Serial No. 842,839.

To all whom it may concern 1 Be it known that I, ROBERT PAUL GELL- RICH, a subject of the German Emperor, and residing at Bullerdeich, Hamburg 35, Germany, master smith, have invented certain new and useful Improvements in Tug- Gears, of which the following is, a statement. r

The hitherto known tugging gears for automatically slipping the hawserhave the great disadvantage, that their mechanism is much too complicated, and can he brought into operative position only with the aid of several persons, so that inconvenient delays are caused, which may even lead totrouble, as it will easily occur that parts ofthe complicated tugging gear hitch or catch and do not close up together. These tugging gears, furthermore, have the disadvantage of not being able to prevent the tug-boat from cap; sizing.

The object of the present invention is to provide a tugging gear for automatically slipping the hawser and preventing the cap sizing of the tug-boat if the hawser should sheer to one side. This tugging gear will not only avoid the disadvantages of the gears heretofore known, but also affords considerable advantages over the latter, in particular by the fact that also when the hawser is slipping automatically, a capasizing of the boat is prevented.

Another feature of the present invention consists in its greatly reducing the purchase rlce. p In the accompanying drawing the present invention is exemplified.

Figure 1 is a side elevation of the tugging gear fitted to a tugboat. Fig. 2 is the tuggear on an enlarged scale in closed position. Fig. 3 is the tug-gear according to Fig. 2, in opened position. Fig. 4 is a top view of the tug-gear fitted to a tug-boat, with the hawser sheered out to the one side. Fig. 5 is a section on the line AB in Fig. 4:. Fig. 6 is the same section as in Fig. 5, but showing the tug-boat heaving over the side.

The tug-gear according to the present in vention consists of the tug-gear proper hav ing the shape of tongs, and the two suitable bent guide supports r and t, which are fitted in a suitable manner to the body of the boat and serve as guides for thetug-gear. The tug-gear is secured to the support 1' by means of a strap p which is hinged by means of a bolt 9 to the lower leg (1, while the support If is disposedhetween the two legs. a and Z), and thereby prevents the whole gearfrom dropping. To the frontflend of the leg a is pivoted on apin n a finger Z, over which the ring o of the hawser 1s placed, and

which is so arranged that its tongue'z'engages in the bore 0 in the legb, thus form- 1ngan eye-shaped mouth 21/, from which the hawserring cannot slip unintendedly.' The finger Z is locked in positionby means ofa toggle joint .9, the upper member of which is made in form of a lever bar it. This toggle joint is pivoted to the legs a and b by means of the pins (Z and'e respectively. hen the toggle lever is stretched, the tongue 2 of the finger Z will be held in thebore 0 of the leg 7), so that the finger cannot be opened. When i the toggle joint 8 is foldedby means of the lever it, the members of said toggle lever fold together and the upper arm 6 is lowered, so that the mouth a is opened; the bore 0 then disengages from the tongue 2 of the finger Z and the latter falls over under the pull of the hawser w, whereby the latter is automatically slipped. For the purpose of 1 allowing of slipping the hawser also from the wheel, the toggle lever s is coupled to arope is, and a short pull on this rope will be sufiicient to fold the toggle and slip the hawser. hen in stretched position, the toggle lever s engages in the forked lug 2' of the leg 6, and bears against a stop If the hawser should sheer to one side, and the boat also heave over to this side, the support 25 will bear on the leg at of the tuggear, which is held in'position by the strain on the hawser, and is supported by this leg so that the boat will not heave overany farther and its capsizing is prevented.

By the arrangement of. this simple tuggear it is, on the one hand, possible to automatically slip the hawser, and on the other hand, a capsizing of the tug-boat is prevented. Lastly its cheap manufacture will reduce the purchase price.

Iclaim: I

1. Tug-gear for automatically slipping the hawser and for preventing the capsizing of the tug-boat if the hawser should sheer to one side, comprising a tug-gear proper composedof two legs forming a shear, the

lower of, said legs having a finger adapted to receive the ring of the hawser and pivoted to said. lower leg, said finger engaging with a tongue in a corresponding bore in the upper leg of the shear, a toggle-lever, adaptends of the legs and disengage said finger' from said bore.

2.T11g-gear for automatically slipping the hawser and for preventing the capsizing of the tugboat, if the hawser should sheer to one s de, comprislng a tug-gear proper composed of two legs form-111g a shear, the lower of said legs having a finger adapted to receive the ring of the hawser and piv-- oted to said lower leg, said finger engaging with a tongue in a corresponding bore inthe upper leg of the shear, a toggle-lever, adapted to hold said finger in engagement with said bore, when in stretched position, the one member of said toggle lever having the form of a lever adapted to fold said toggle lever and thereby also close the rearward ends of the legs and disengage said finger from said bore, a guide support fitted t0 the body of the ship and adapted to bear on the tug-gear under the strain of the hawser and thereby prevent the capsizing of the boat.

In testimony whereof I have hereunto set my signature in the presence of two subscribing witnesses.
